Vitamin D Test

A simple at-home blood test to find out your current vitamin D level and get personal guidance on how to support it.

The Zinzino Vitamin D Test analyzes a dried blood spot sample from a fingertip, using just 1–2 drops of blood. Results are shown in an easy-to-understand format and help you see whether your vitamin D level is optimal, too low, or too high.
